Updating Facebook App

I've been reading all over the place that the Android Facebook app just rolled out an update with UI enhancements etc. I haven't received the update notice on my Moto Droid yet so I decided to go to the market and search for it, but when I find it, it only gives me an option for "install" as if i didn't already have it installed, but i do have it installed. It came installed on the phone. What's the deal? Do I need to uninstall my stock facebook app and install the one from the market?
